I was pulling slowly into a parking space and my 2004 Sienna van uncontrollably accelerated and smashed into a building.

- Manchester, MA, USA

Van was put in reverse and it accelerated on its own and hit car behind, quickly put it on drive and w/out pressing accelerator, it surged forward. Luckily there were boxes between the van and the wall. Brought it to Toyota, said they found nothing wrong with the van and that the warranty wont cover.

Toyota 2004 le Sienna. Driving on straight, dry, road about 30-40 mph. Vsc suddenly light turned on unexpectedly, followed by loud beeping noise. Van appeared to hesitate. Can't go more than 40 mph. I was glad that there was no car behide me otherwise there would have been an accident. Van was brought into dealer (Toyota of palo alto, ca). They found no error code.

: the contact stated intermittently while applying brake pressure, the pedal will go to the floor. In addition, the vehicle accelerated without warning causing an accident. One person sustained minor injuries and there was a crash and property damage. The vehicle was taken to the dealer where the problem could not be duplicated and the contact was informed that the vehicle is functioning normally.

Radiator ruptured and the engine overheated; hose replaced in steering column recall; rust protective tape recall; dvd screen replaced and the entire dvd player replaced(screen still not easily visible in middle row); passenger seat belt replaced; middle passenger seat belt failing; gasoline smell inside of car with ac on recirculation; driver's window fell inside door in snow storm and was not considered a safety issue to get a loaner vehicle even though the vehicle could not be locked; tires completely bald and leaking under 30,000 miles, dvd player must be at a high db volume and when returned to radio/cd will almost deafen you; interior lights have to be manually over ridden or will drain battery; car hesitates 1-2 seconds when trying to quickly accelerate and then lurches forward alarmingly; cruise control is not functioning; waiting to have fuel mixture sensor replaced. I was not informed of first 2 recalls until I my engine overheated. I did get the rust recall and a sticker on my sliding door informing user of danger of having middle windows open while opening the middle door could catch a head or other extremity. Toyota dealer service manager says mine is the only 04 Sienna experiencing any problems except for the recalls on the radiator; the steering hose; the rust tape; and the middle seat belt. Not so according to all I have read here. Most of the problems have occurred between 22,000 and 34,000 miles; the dvd screen always failed to lock into a good position for the middle row viewers.

As I was driving on a dry road at about 30 mph the vehicle speed control (vsc ) indicator light went off, followed by a continuous beeping from the dashboard, by a vibration of the vehicle (more the left side) and by an automatic intermittent application of the brakes on selected tires as if the minivan was trying to regain control and pulling towards the left. The minivan immediately slowed its speed to less than 5 mph and when tried to reapply for acceleration, as soon as exceeded 5 mph the beeping restarted, the light went off again and the pulling to the left and the automatic breaks were applied. The vehicle had to be towed to the dealership where is still under repair. Apparently they indicate there is a tsb related to this matter.

Driving approximate 45 mph on straight, dry and clear residential road when vsc indicator illuminated and rapid beeping occurred. ABS proceeded to kick in causing vehicle to lurch while moving. The brakes will apply themselves while driving at a particular speed. Which then enalbe you from driving at all. This is the third time this has happened. The first two times the dealer could not reproduce the problem, and there was no error code on the onboard computer so no fix could be made. The final time we cited tsb BR08-04 (after much searching on the web) and they agreed to replace the steering angle sensor.

- Brampton, 00, USA

Vsc activates while vehicle is traveling straight. This can and has caused the vehiscle to shift lanes and stop short. It has happened a dozen times and the dealer is not able to diagnose this.

There is a distinct delay in the acceleration of my 2004 Toyota Sienna van when the accelerator pedal is depressed quickly. This delay is not noticeable unless the driver is already moving and the accelerator is depressed in situations such as passing or some other activity that requires quick acceleration. I was trying to speed up while driving in the right hand lane of a highway because the left lane was already occupied and a vehicle was attempting to merge onto the roadway. My van did not speed up until it was too late and the vehicle attempting to merge onto the highway drove off of the road to avoid an accident. During another occasion requiring quick acceleration a truck locked up its' brakes to avoid hitting me from behind when I merged into his lane as I depressed the accelerator only to have the van fail to speed up for two seconds. Toyota personnel from the dealership where I purchased the van (world Toyota of chamblee, ga) informed me that they have received similar complaints but they are unable to correct the problem because it is the result of a design flaw in the vehicle in that Toyota installed a laser control on the accelerator in lieu of an accelerator cable that could be adjusted.

2004 Toyota Sienna exhibits poor low speed drivability when accelerating from slow speed. Throttle does not respond to pedal action which results in unpredictable acceleration time and amount. Poor, or no, engine response is followed by lurch forward as throttle (over) reacts and transmission searches for the proper gear. Many 'near misses' in traffic merging situations. The primary driver, my wife, will no longer use this vehicle. Several dealers have reviewed this issue and state that Toyota classifies this performance as a 'characteristic' of the 3.3L platform. This performance is not acceptable to me and vehicle will be replaced if not repaired soon.

While parking, accelerating no more than 5 mph vehicle surged forward. Although I was applying the brake, the car would not stop until it ran into a tree trunk. I will be making an appointment with oakbrook Toyota in westmont, il to replace the broken foglight that occurred during the collison as well as research the problem and hopefully apply a fix.

I noticed an article recently about a probe into Toyota's (Camry and Lexus) that surge. My 2004 Toyota Sienna surges forward when braking and though it does not do this consistently, it happens every so often and could potentially cause an accident. I have reported this to the dealer and they have examined the vehicle and said that there is nothing wrong. My personal experience with the electronic throttle control is that not only does it surge when braking, there is also a delay in the signal when accelerating that either causes an unsafe delay in entering into traffic and can also cause the vehicle to "peel out" from a stopped position. I basically feel unsafe in this vehicle, yet my concerns voiced to the dealer have been dismissed. This defect needs to be seriously monitored in Siennas as well as other Toyota with the electronic throttle control.

Engine idles very fast in cold weather first few minutes. While driving a block to the first stop sign has to apply the brakes very forcefully to get the car to stop. This causes some loss of control, especially on a slight down hill slope during snowy/icy weather. Appears to be combination idle, and the automatic transmission.

- Geneva, IL, USA

Vehicle hesitates/fails to move forward in the following mode: After braking, when the vehicle is still moving between 5 to 15 mph, the van does not respond to accelerator pedal input; vehicle hesitates with no movement forward, then shifts hard into first gear and lurches forward. We have had 2 close calls, waiting for the vehicle to respond to accelerator pedal input. Also, accelerator pedal has a dead spot. The first half inch of pedal causes no response from vehicle). This "dead spot" along with the hesitation noted above can result in a 2 second response failure from the vehicle. This situation has put my family in harms way on numerous occasions.

When driving at an undetermined speed vehicle surged. Consumer took the vehicle back to the dealership for inspection.

Recurring drivability problem with 2004 Sienna xle 3.3L. After decelerating then reapplying throttle, surge varies from annoying to dangerous. On occasion, is severe enough to squeal tires. From a dead stop, throttle response is better but from a rolling stop, dangerous and inconsistent.

- Southbridge, MA, USA

While parking, the vehicle surged forward. As a result the vehicle collided into a fence. The dealer stated they were unable to duplicate the problem. Please provide additional information.

- Auburndale, MA, USA

2004, Toyota Sienna xle limited. Very sluggish throttle response when cruising, apparently due to very sluggish automatic transmission down shift. No problem when accelerating from a stop. Problem is bad enough to cause an accident when the driver expects reasonable throttle response to avoid a collision, such as crossing an intersection.
